Abstract

L'invention concerne un procédé et un dispositif de traitement de service. Dans le procédé : une passerelle de desserte (SGW) détermine la survenue d'une exception sur une passerelle de données par paquets (PGW) et obtient une politique de suppression de connexion de réseau de données par paquets (PDN) établie entre la SGW et la PGW ; la SGW supprime la connexion PDN entre la SGW et la PGW, d'après la politique de suppression de connexion PDN, et envoie un message de demande de suppression à une entité de gestion de la mobilité (MME), le message de demande de suppression contenant des informations d'identification de la connexion PDN supprimée, pour signifier à la MME de supprimer la connexion PDN correspondant aux informations d'identification. Quand une SGW détermine la survenue d'une exception sur une PGW, comme il n'est pas nécessaire d'envoyer des informations indiquant la survenue de l'exception sur la PGW à une MME, une quantité de transmission de signaux dans un système est réduite et un flux de traitement de service est simplifié. De plus, l'utilisation d'une autre politique de suppression accélère la vitesse et améliore l'efficacité du traitement de service du système, ce qui améliore l'expérience utilisateur.
